A snap button for attachment to a cloth is composed of male and female buttons engageable with each other. Each of the male and female buttons includes a face plate centrally from which a smashable shank projects, a snap body, and a resilient plate. The snap body has a respective one of concave socket and plug portions in which an axial shank-insertion hole, and a peripheral flange extending from a base portion of the plug and socket portions off an inner open end thereof. The resilient plate is adapted to be pierced by the shank so as to clamp the cloth between the face plate and the resilient plate. As a result, the cloth is held not only between the resilient plate and the shank but also between the shank and the snap body, and this clamp structure prevents the cloth from being removed off the each of the male and female buttons.

Cette invention concerne un bouton pression à fixer à une pièce de tissu. Il se compose d'un élément mâle et d'un élément femelle destinés à se mettre en prise l'un avec l'autre. Les deux éléments comprennent une plaque de parement portant une tige écrasable centrée, un fermoir et une plaque élastique. Le fermoir de l'un des éléments présente une douille concave et celui de l'autre un culot également concave. Les deux comportent dans cette partie un trou destiné à recevoir la tige écrasable susmentionnée. Les deux fermoirs comportent également un rebord périphérique partant de la base de la douille ou du culot respectivement. La plaque élastique est conçue pour être percée par la tige susmentionnée et pour pincer le tissu entre elle et la plaque de parement. Ainsi, le tissu est maintenu non seulement entre la plaque élastique et la tige mais aussi entre la tige et le fermoir, d'où l'impossibilité que le tissu se détache des éléments mâle et femelle du bouton pression.
